Tesing my app with FB1.5 (was IB) and IBO 4.3.A. Using implicit
transaction control with db commits after inserts and updates.
AutoCommit is true.

Error 1: "Multiple rows in singleton fetch" The select statement is
requesting one row and the key is the primary key field? Keylinks is
the primary key field. What would cause this?

Error 2: ISC ERROR CODE:335544332 Invalid transaction handle
(expecting explicit transaction start)?? A simple update query
setting one field to zero with the primary key field as the key.
Keylinks is the primary key field.
